PtahCast for Mac

Project management with the forecast built in

Know when it will really be done.

Plan on a board, in sprints or on a waterfall roadmap. PtahCast reads how fast your team actually finishes work and tells you when the rest will be done, with a confidence level. No estimates, no story points.

Probabilistic forecasting

An answer you can plan around: a range, not a single date.

Every week PtahCast counts the tickets you finished. It replays that pattern thousands of times against the work still open, then reports how likely each finish date is.

P5029 DecEven odds. Plan on it only if a miss is cheap.
P708 JanLikely. Good for internal targets.
P8519 JanSafe to promise to a client.
P952 FebAlmost certain. Use for hard deadlines.

Example forecast for a project with 60 open tickets.

When will it be done?

Dates at 50, 70, 85 and 95 percent confidence for the work that remains.

How much by a date?

Pick a date and see how many tickets you can count on finishing by then.

What if?

Change throughput or scope and compare scenarios side by side. A new project can start forecasting before it has history.

Was I right?

Log each forecast with your commitment date. The accuracy card shows how often reality landed inside it.

One tool, any method

Run it as Kanban, as sprints, or as a waterfall plan.

Same tickets, same epics, same forecast. Each project manager picks the view that matches how they work, and can change their mind midway.

Kanban: flow, measured

Drag cards across your columns. PtahCast records when work starts and finishes, so the board feeds the forecast without any extra effort.

  • Columns of your own, with work-in-progress limits that warn you before the team overloads.
  • Started and finished dates are recorded when you move a card.
  • Flow metrics: throughput, cycle time, work item age and cumulative flow.
  • A live answer to "when will the backlog be done?" at the top of the project.

A look inside

Six screens that do the work.

Everything a project needs

A complete project system, not just a forecaster.

Five ways to see the work

Board, sortable list, epics with progress, calendar and roadmap, all on the same data.

Find anything fast

Search titles, descriptions, tags, comments and checklists. Filter by epic, iteration, assignee, priority, tag or status.

Tickets with substance

Checklists, blocked-by and related links, a blocked flag, due dates, tags, comments and attached file links.

People and weekly packs

Assign tickets, flag this week's work, and send each developer a PDF of their tickets with the attached files from your own mail app.

Import and export

Bring tickets in from Excel or CSV with a ready template. Export the list to Excel or CSV. Back up and restore a whole project as one file.

Private by design

One person, one Mac. No account, no cloud, no seats. Your projects stay on your computer.

For your client 4 PDFs

Delivery forecast, progress by epic, completed this period, and forecast history. They show dates and progress, never your internal detail.

For your team Internal

Risks and blockers, forecast accuracy, workload by person and flow health. Internal reports can never go to the client address by accident.
